BLANCHARD CHAMBERLAIN, OF BELLEFONTAINE, OHIO, ASSIGNOR OF ONE- HALF TO FRANK J. SCARFF, OF SAME PLACE.

ANTI-RA'-'TLER AND SHAFT=SUPPORT FOR THlLL-COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 321,190, dated June 30, 1885.

Application tiled April 24, 1885. (No model.)

T all whom, it may concern.-

Be it known that I, BLANCHARD CHAMBER LAIN, a citizen of the United States, residing at Bellefontaine, in the county of Logan and State of Ohio, have invented a new and useful Combined Anti-Rattler and Shaft-Support for Carriages, of which the following is a specification.

The object of my invention is to provide a combined anti-rattler and shaft-support for bnggies and other carriages, of simple and effective construction, and not liable to get out of order. My improved anti-rattler dispenses entirely with the need for gum springs.

It consists, essentially, of a steel spring of a partial helix or scroll form, fastened tothe under side of the shaft-iron by the same bolt which secures the heel of the shaft thereto, and by reason of the helical or gradually-increasing curvature from its heel toits free end adapted, when the shafts are elevated, to be partially relieved of pressure, but apply sufficient friction to support the shafts in the elevated position, and when the shafts are drawn down to press with increasing force against the face of the axle-clip, partially supporting the weight of the shafts and serving as an effective anti-rattler.

In the accompanying drawings, Figure I is a plan orA top view of the heel portion of a buggy-shaft and a part of the customary axleclip and shaft-coupling with my improved anti-rattler applied. Fig. II is a side View of the same, the axle being shown in transverse section, and the shaft in position for use. Fig. III is a section of the same parts with the shaft elevated.

The axle 1, clip 2, with itsjaws 3, the shaft 4, shaft-iron 5, and coupling-bolt 6, may all be of usual construction.' .By the bolts 7, which attach the shaft 4 to its coupling-iron 5, I secure beneath the shaft-iron 5 my anti-rattler spring 8, which is formed of a plate of steel bent in helix or scroll shape, or with a curve lessening in radius toward its free end.

The

helical or scroll bend imparted to the antirattler spring adapts it to bear against the face of the clip 2 with increasing force as the shafts are drawn down to position for use, as illus` trated in Fig. II, the pressure of the spring against the face of the clip forcing its end down upon the eye of the shaft-iron or against the heel of the shaft, so that it holds the parts firmly in place and forms a perfect antimattler. When the shafts are elevated, the spring is relieved from the cramped position necessary to make it serve effectively as an antirattler, but still presses at a point nearer its outer or free end sufficiently hard against the lower part of the face of the clip to hold the shafts in their upright position until they are drawn down by force greater than their own weight.

It will be observed that the antirattler spring, when once fixed in position, never needs to be moved, and that it offers no obstruction or difficulty in applying or removing the shafts or the pole, as the case may be.

Having thus described Iny invention, the following is what I claim as new therein and desire to secure by Letters Pat-ent:

l. An anti-rattler and shaft-support consisting of a metal spring bent in scroll or helix form tov adapt it to exert pressure to hold the shafts against rattling when they are drawn down in position for use, and to support them when they are elevated, substantially as herein set forth.

2. In combination with the shaft-iron 5 and axle-clip 2 3, the scrolllspring 8, bolted by its base to the shaft and shaft-iron, bearing in one direction against the face of the clip to support the shafts when elevated, and contracted by the drawing down of the shafts so as to bear also against the heel of the shaft or shaft-iron, as explained.

BLANCHARD CHAMBERLAIN.
